Protection & Hot Swap Controllers

No, 3.3VAUXIN (Pin 14) is also used to power the internal control logic and analog references of MAX5954, and must be connected to a 3.3V power supply.

The IC is design for DC application and can only be used as a DC circuit breaker. However, you can use it as AC circuit breaker if the AC is rectified to DC.

The UVLO pin should not be left floating. If the user prefers to not use the UVLO function through the UVLO pin, and plans to use the “Internal Undervoltage Trip Level” instead, then the UVLO pin…

The MAX16141 triggers the reverse current threshold by sensing the voltage between OUT and IN pins. Decreasing the sense resistor would not change the threshold level but will cause extra current to flow…

During SLEEP mode the internal PMOS is a current source, you cannot damage it by adding more load current. It will just cause the output voltage to collapse. It will self limit the current.

Kindly note that TMR1 and TMR2 are used for Overcurrent time out, which disconnect the input from the output if fault is detected. However, if you want to disable this Pin, you can ground it.

If you don't intend to use OVLO, set this threshold voltage to be the maximum voltage allowed. To do this connect VRef to Vin and set R3 and R4 = 2.2MΩ. This way you set OVLO to the max voltage (Vin) and…

On page 9 of datasheet in "current limit response" figure, Vout is not Zero till 24ms from the time short circuit occurred. Only after 24ms the Vout has completely gone to zero, i.e when switch is OFF…
